What Expansion Do You Play With The Most?

I'm in the boat where technically, this is actually an almost impossible choice for me to really make as I not only love and heavily use the content in each pack but also incorporate the gameplay each pack introduced into my game very heavily. I ultimately chose Island Paradise in part because it seems to be the pack I had been playing the most with recently in terms of features it introduced as well as just the new world it gave us. However, so many on that list could easily have been up there as well! Had there been an option for all of the above, that actually would have been my choice but I also understand the 10 option limit came into play.
